DIE ROLLER.

Application filed May 26, 1922.

State of New York, have invented an 1100-.

provement in Die Rollers, of which the following description, 111 connectlon with the accompanying drawings, 1s a specification,

like characters on the drawings representing like parts. i

This invention relates to die rollers and particularly to die rollers for material of dough-like consistency.

In order that the principle of the invention'may be readily understood, I have disclosed a. single embodiment thereof in the accompanying drawings, wherein Fig. 1 is a side elevation, with parts broken away and in vertical section, of a die roller embodying my invention;

Figs. 2 and 8 are vertical transverse sections upon the lines 2-2 and 33 respectively of Fig. 1;

Fig. i is a plan View of one of the die blocks; and

Fig. 5 is avertical longitudinal section taken through the die roller.

A die roller, such as herein disclosed, may be used for many purposes, but is of particular utility when used upon material of dough-like consistency, and especially upon food products material.

Heretofore so far as I am aware, it has been customary to provide a die roller with a plurality of die blocks, but the blocks have been assembled in such manner as to render it very diilicult to remove a defective block, and especially without disassembling or taking down the entire roller and its several parts.

The die roller of my invention is so constructed that any defective die block can readily be gotten at and removed, a substitute block be positioned in place thereof and the parts of the roller re-assembled in proper position with a minimum expenditure of effort and time.

lVithout limiting myself to that embodiment of the invention herein shown, I will describe the preferred embodiment of my invention.

I provide a shaft 1 desirably having a key extending substantially the length of the roller and also desirably having a key to hold fast upon the shaft a gear or driv- Serial No. 583,813.

ing member, such as 2. I provide two heads 3, 4, both of which have openings 5, 5 for the reception of bolts 6 extending substantially the entire length of the roller and receiving nuts 7.

I provide a series Any suitable number of such rings may be employed. Herein I have represent-ed eight rings each at its surface being of the full width of a die block, one of said die blocks being represented at 9 in Fig. 4.

Each of said die block rings is of po-. lygonal shape, each being herein shown as having twelve faces, though obviously within the scope and purpose of my invention, any suitable number of faces may be provided. Each die block is provided upon its face with a suitable die formation 10, preferably embossed thereon, and which forms no part of my present invention and may be varied as desired. A suitable number of screw holes are provided in each face of each die block ring as indicated in Figs. 2 and 3, four screw holes being preferably provided so that screws 11 may be received therein and enter screw holes 12 extending part way through only from the under faces of the several die blocks 9 at both sides of the radial supporting web. In this manner the several die blocks are held securely in position, eachupon a separate face of the die block ring to which it pertains. As shown, the die blocks of a single ring abut at their ends and the die k rings 8.

blocks of adjoining rings abut at their sides.

block is reached. This allows space for access to the inside of the die block ring having the defective die block so that the screws 11 therefor may be removed, the de fective die block taken out and another substituted therefor.

As shown, each ring 8 has a web 18 ex tending from its polygonal face inward toward its hub or centre 14:. This web may be of sufiiciently less thickness than the polygonal faces of the ring to provide space for the screw holes and for the manipulation of the screws 11, the said web 13 being therefore preferably central with respect to the several polygonal faces thereof.

Obviously the .die roller constructed in accordance with my invention may be used in any suitable manner. Accordingto one manner of use the roller is positioned at the bottom of a hopper containing dough, the dough being drawn by the die roller between, itself and a contacting roller, and in the continued rotation of the die roller the cakes or other products are separated from the die roller in any suitable manner not constituting a part of this invention and which therefore need not be described, inasmuch as such means are well known in the art.

The die roller of my invention is particularly .useful in connection with a dough of such rich consistency that it would fall apart if handled. Obviously the dough product may be wafer, either filled or unfilled, or any other suitable product.

I have stated that each die block ring may have any suitable number of faces. Within the scope of my invention, the ring may be circular and receive the die blocks thereon, each block having its inner face curved to correspond to the circular or like formation of the die block ring. I have employed the term polygonal throughout the specification as including a circle.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.

Claims 1. A die roller comprising in combination, a shaft, a pair of heads keyed thereon, a plurality of die block rings positioned in a laterally adjoining relation between said heads, bolts passing through said heads and rings to confine the parts in assembled position, each ring having a polygonal surface, and a series of die blocks detachably secured to the polygonal faces of each of said rings.

2. A. die roller comprising in combination, a shaft 1 having a driving gear 2, a pair of heads '3, at keyed upon said shaft and adapted to be slid therealong for assembling or disassembling the parts of the roller, a series of die block rings 8 likewise keyed upon said shaft 1, each ring having a radial web 13 and polygonal faces constituting the periphery thereof and a series of die blocks 9 secured by screws 11 inserted from the inside of the said polygonal faces, and bolts 6 for securing the said parts of the die roller in position.

3. A die roller comprising in combination a shaft having driving means, a pair of heads keyed upon said shaft, a series of die block rings positioned between said heads, means extending through said heads and rings for securing the parts in assembled position, each of said rings having a radially extending web, and relatively broad guide block receiving faces, and embossed die blocks detachably secured to the several faces of said roller, the several die blocks of single ring contacting at their ends and the die blocks of adjoining rings being in lateral contact.

4. A die roller comprising, in combination, a shaft, a pair of heads thereon, a plurality of die block rings individually surrounding said shaft between said heads and held in position thereby, each of said rings having a hub keyed on said shaft, a relatively narrow radial web portion extending from said hub and a relatively broad cir cumferential surface to receive a plurality of die blocks, die blocks detachably secured in a series to the surface of said ring and means extending longitudinally of the shaft and connecting said heads together and thereby securing the rings in position.
